Problems solved by technology

This method is obviously more optimized than other solutions, but there are still two problems: one is that the role of the GGSN at this time is only an auxiliary device of the SGSN, and its existence itself is a waste; the other is that the GGSN can only communicate with its nearest The interconnection of SGSN limits the capacity of GGSN to not exceed the capacity of SGSN, but the actual situation is that the capacity of GGSN is usually much larger than that of SGSN; the problem is more prominent when backup between GGSNs is required, because at this time the SGSN is required to be deployed nearby More than two GGSNs, which will cause further waste of GGSN capacity

Embodiment Construction

[0039] The core idea of ​​the present invention is to direct ordinary Internet services through the SGSN to the Gi interface to provide service access to the Internet to improve the utilization efficiency of network resources, so as to meet the requirements of high-speed wireless access technology for the processing capacity of the core network.

[0040] The invention provides a method for improving the utilization rate of network resources in a wireless communication system. The SGSN directly sends out the Gi interface, avoiding the mutual interference between the service flow sent to the Internet and the service flow sent to the VPN, and at the same time reducing the waste of resources.

[0041] refer to Figure 6 Shown, be the common Internet service processing flow of the present invention, this flow comprises:

[0042]Step 10: The MS sends a PDP (Packet Data Protocol, packet data protocol) activation request to the SGSN end;

[0043] The CTL (control plane entity) in the...

Abstract

The invention relates to a method for increasing utilization ratio of network resources of wireless communication system by supplying data flow directly through SGSN to Gi interface to Internet service access, to adapt to the requirements of high speed wireless access technique for kernel network processing ability. And it makes the data flow reach Internet only through SGSN but VPN services reachVPN through private network and GGSN, not only saving GGSN resources but also reducing interference to private network services, simplifying networking and having no influence on protocol.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for improving network resource utilization of a wireless communication system. Background technique [0002] In a typical WCDMA (Wideband Code Division Multiple Access) network, packet domain user plane data needs to pass through NODEB (base station)-RNC (radio network controller)-SGSN (serving GPRS support node)-GGSN ( Gateway GPRS support node) can enter the Internet through the Gi interface, especially when the SGSN and GGSN are not placed nearby, common Internet services increase the waste of transmission resources between SGSN-GGSN and GGSN resources. [0003] Such as figure 1 Shown is a typical WCDMA packet domain user plane network structure diagram, in which the data packets of the terminal MS (mobile terminal) will be sent to the Internet or VPN (virtual private network) network from the Gi interface through NODEB, RNC, SGSN, and GGSN. The opposi...
